Breathing insole with ventilating function

ABSTRACT

This invention relates to a breathing insole with ventilating function, which is made of the shoe-shaped upper &amp; lower insoles and porous layer; its features are as follows: when the upper insole is molded, the containing trough is made in concave in the central part of its bottom according to shape of shoe, frame around containing trough is also formed so that upper and lower insole are glued and form an air chamber. Several elastic protruding bodies are fixed in the arch of containing trough of this upper insole; porous layer contacting sole of the foot is glued onto upper insole. In addition, based on upper insole and porous layer, several inlet holes and outlet holes are respectively made in the heel portion and in the front thenar portion of foot; as the breathing insol with ventilating function is placed into shoes, the continuous trample and lift-up by the shoe wearer while walking may push cool air around the heel portion into the front thenar portion of the foot, the wet and hot air around the front thenar portion of foot inside shoe can be exhausted, therefore, shoes may keep ventilating and discharging heat effectively.

BACKGROUND OF THE INVENTION

1) Field of the Invention

This invention relates to a breathing insole with ventilating function, in which, a concave containing trough in the central part of the upper insole with frame is glued to the lower insole so as to shape an air chamber based on potential difference. Several elastic protruding bodies are fixed at the arch of containing trough of upper insole in order to fend off air chamber, so as to increase the room of air chamber, the upper insole and porous layer gluing onto upper insole and contacting the sole of the foot, several inlet and outlet holes are designed at the heel portion and the front thenar portion of the foot; thereby, the trample of the wearer, can circulate air to keep shoe ventilation.

2) Description of the Prior Art

Usually, when the wearer put on shoes and socks, heat and sweat will be produced while walking. The inside air of the shoes is difficult to exhaust, when the temperature is high. Therefore, the wearer may feel uncomfortable, the feet of wearer may stink, furthermore, the wearer may have the annoying Hong Kong foot due to multiplying of mildew, so, it is the vital subject for shoe producer to solve the problem of wet and heat; However, the current methods to improve ventilation of shoes are many, the insole with ventilating function, such as U.S. Pat. No. 4,215,492U.S. Pat. No. 5,010,661 and U.S. Pat. No. 5,333,397, which fix elastic envelope at the heel portion of the foot with different methods. And they set inlet holes at the heel portion or rear edge of the heel portion, set outlet holes at the front thenar portion of the foot or the region of the toes of the wearer, the continuous stepping down and lifting up by sole of the wearer walking may push cool air around the heel to enter into the front thenar of the foot, exhaust moist, muggy air around the front thenar of foot inside shoe, therefore, the shoes may ventilate and release heat. However, this model of product has limited air contents due to small fend-off envelope, the thickness of insole must be increased if you want to add air contents, so, it isn't applicable for common shoes. Another example, such as the U.S. Pat. No. 4,224,746, which is an insole with ventilating function, it use a member formed of a resilient, porous material enclosed in an impervious envelope having a plurality of air inlet ports near the rear edge of its heel portion and a plurality of air outlet ports in its front thenar portion in the region of the toes of the wearer of the shoe. Such a construction, in addition to cushioning the foot, provides for drawing cool air into the toe region of the shoe as a result of the normal walking action.

The envelope supported by such sponge elastic body uses interval of sponge to contain air, so, its air contents may be reduced, and this supporting body may be fatigued due to the extrusion of the wearer weight. The above described data are ineffective, hereby, we will put forward an improved insole which is light and thin with large air contents and effective ventilating function, and it is applicable for all sorts of shoes.

SUMMARY OF THE INVENTION

The purpose of this invention is to provide a breathing insole with ventilating function, wherein a concave containing trough in the central part of the upper insole with frame, upper and lower insoles are glued together so as to shape an air chamber which is based on potential difference. Several elastic protruding bodies are fixed at the arch of the upper insole in order to fend off air chamber. The porous layer is glued onto upper insole, several inlet and outlet holes are designed at the heel portion and the front thenar portion of the porous layer and upper insole; thereby, trample of sole of the wearer can circulate air while walking, so as to keep shoes ventilation.

The second purpose of this invention is to provide a breathing insole with ventilating function, wherein the structure of this invention is simple and without any assistant component (such as air valve, air guide pipe), insole itself forms air chamber, and the insole is light & thin and large air contents, therefore, it can not only exhaust large quantity of air, but also is comfortable to wearer.

The third purpose of this invention is to provide a breathing insole with ventilating function, wherein, the molding of the upper insole of this invention can save workload and material, its cost of production may be reduced.

The fourth purpose of this invention is to provide a breathing insole with ventilating function, When a concave containing trough in the central part of the lower insole with frame, and concave containing trough can be designed equally distributed protruding points in the lower insole and the porous layer are glued together so as to shape an air chamber. Several elastic protruding bodies are fixed at the arch of the lower insole in order to fend off air chamber, several inlet and outlet holes are designed at the heel portion and the front thenar portion of the porous layer; thereby. The wearer can be easier to exhaust moist muggy air on foot while walking, so as to keep shoes ventilating more effectively.
